> RMNode#ReconnectNodeTransition has messed up for every ReconnectedEvent. This part of
the code can be clean up where we do not require to remove node and add new node every time.
> Supporting to above point, in the issue discussion YARN-3222 mentioned in the comment
and [link2|https://issues.apache.org/jira/browse/YARN-3222?focusedCommentId=14344739&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14344739]
> Clean up can do the following things
> # It always remove an old node and add a new node. This is not really required, instead
old node can be updated with new values.
> # RMNode#totalCapability has stale capability after NM is reconnected.
